Description: 数字频率计作为一种常见的应用电子仪器设备，传统的一般可以完全由硬件电路搭接而成，如采用基于555 定时器电路的多功能数字频率计的设计便是可取的路径之一，不用依靠单片机。但是这种电路存在一些缺点，且测频精度也不如单片机的高。在科学研究和生产实践中，如工业过程控制，生物医学，地震模拟机械振动等领域常常要用到频率计。利用单片机采用程序设计方法来设计频率计，其测频精度高。且线路相对简单，结构紧凑，价格低廉，系统稳定度高，抗干扰能力强，用途广泛等优点-Digital frequency meter is a common application of electronic devices, the traditional general can completely by hardware circuit lap, such as the use of 555 timer circuit based multifunctional digital frequency meter design is the one of the desirable paths without by MCU. But this circuit has some shortcomings, and the accuracy of frequency measurement as well as the MCU high. In the scientific research and production practice, such as industrial process control, biomedicine, seismic modelingmechanical vibration and other fields often use frequency meter. The use of single-chip microcomputer to design frequency meter program design method is adopted, the frequency measurement precision. And the lines are relatively simple, compact structure, low cost, high stability, strong anti-interference ability, wide range of uses, etc. Platform: |
